- INVENTOR ATTORNEY Patented May 23, 1933 PATENT orrica ALBERT R. DANIELS, OE FORT SAM HOUSTON TEXAS Application filed August 3,

This invention relates to certain new and useful improvements in loose-leaf books and the like and which embodies among other characteristics an arrangement by means of which the different leaves maybe removed and replaced without disrupting the binding.

Another object of the invention contemplates the provision and arrangement of loose leaves of this character having incised eyelet openings in communication with the top and bottom edges of the leaves to prevent accidental displacement of any one of the several leaves when the book is being carried. F Another of the major objects of the invention consists of an adjusting means for the binding whereby the latter may be slackened or tightened commensurate with the number of loose leaves to be bound.

With the above'and other objects in view, the invention further consists of the followin g novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a perspective view of my improved form. of loose leaf book partly broken away to illustrate the arrangement of the binding and incised leaf openings.

Figure 2 is a plan view of one of the loose leaves.

Figure 3 is a detail sectional View line 3-3 of Figure 1. 1

Figure 4 is an elevation of the back or bind- 5 ing side of the book.

Figure 5 is a longitudinal sectional view taken on line 55 of Figure 1.

Figure 6 is a fragmentary bottom plan view of the book illustrative of the particular means of adjustment for the binding.

Figures 7 and 8 are fragmentary perspective views of the respective sections of the adjusting means.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference characters 10 and 11 indicate the respective covers or hacks for the present form of loose leaf book bound together by a binding element 12 of cross section channel formation. One side wall 13 of taken on Loose LEAF BOOK BINDER 1931. Serial No. 554,866.

the binding'element is longer than the other and extends over and beyond the usual foldmg line for one of the covers, namely, the cover 10 upon the top, and terminates to provide a sleeve 13 upon the side edge thereof overlying said cover to accommodate an' appropriate portion of a wire loop 13 within the bore thereof. Said loop-is also passed beneath the under side of the back 10, substantially as illustrated in Figure 3.

As hereto-fore experienced by users of loose'leaf ledgers, books and the like, there is a tedious task involved in maintaining the book or ledger up to date incident to the insertion of additional loose leaves. This is especially true where lacings are employed as the means for joining the binding, leaves and covers of the book together. It is my purpose, in overcoming the foregoing disadvantages, to provide a loose-leaf book which will permit any one of the several leaves to heremoved and replaced without requiring altera tion of the binding lacing. This is accom- V plished through the arrangement of slots or incisions 14 inwardly directed in alignment from the top and bottom edges of the loose leaves and in communication with the immediate holes 15.

These slots or incisions facilitate passage of appropriate portions of the lacing bind- 30 ing for ultimate disposition within the openings 15 and as will be readily apparent, this form of leaf will not drop out when the book is being carried.

The base portion 16 of the lacing binding has inwardly offset extremities 17 in communication with outwardly and longitudinally disposed attaching ears 18 apertured for the accommodation of rivets or other fastenings 19 for permanently locating said base portion upon the shorter side wall of the binding 12 and the cover 11. The adjustable section 20 of the lacing binding lock is hingedly mounted, as at 21, upon the base section 16 and from which the section may be shifted to occupy the full and dotted line positions shown in Figure 5 of the drawings. As will be noted from the fragmentary perspective views of the complemental sections of the adjustable lacing 1 8 binding apparatus in Figures 7 and 8 of the drawings, members 22 of U-shape formation are alternately arranged for reception within openings 23 for purposes to be better understood in the following description of the invention.

The lacing binding, alluded to in the foregoing, consists of a lacing 24 having one end knotted, as at 25, said knotted end engaging the outer surface of the shorter side wall of the binding 12. Said lacing is then passed through the incised opening adjacent one side edge of the loose leaves and subsequently between the outer surface of the cover 10 and the wider side wall 13 of the binding 12 for ultimate passage through the oppositely disposed incised opening within the opposed side edges of the loose leaves The freeend of the lacing is then laid upon the outer surface of the base or permanent section 16 of the lacing binding lock and the section 20 is then. disposed to occupy the full line position shown in Figure 4' whereby said free end of the lacing will be forced between and in frictional contact with the several U-shaped members 22 and walls of the openings 23. A clamping band 26 slidable along section 16 is employed for the purpose of joining the free end'of the section 20 to the permanent section 16.

The hinge 21 of the section 20 is embedded in the cover 11 so that the outer surface of said section will be substantially flush with the outer surface of the cover when in a closed position as shown in Figures 3, 4 and 5.

The invention is susceptible of various changes in'its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention, what is claimed is:

1. A loose leaf book provided with cover pages for receiving therebetween a series of loose leaves, a lacing for retaining the. leaves between said cover pages, means for locking said lacing and permitting the lacing to be slackened or tightened, said means comprismg a member permanently secured to one of the cover pages and a movable member, said fixed and movable members each being provided with spaced openings, means formed on each of said sections for fitting in the openings of the adjacent section for forcing the lacing through the openings of said sections and effecting a clamping action of the lacing between the sections when the movable section is in closed position.

2. A loose leaf book including cover pages having a lacing for removably securing leaves between said cover pages and one end'of said lacing being secured to one of the cover pages, a base plate carried by one of the cover pages having spaced openings with the lacing overlying said openings, and a movable member hinged to said plate and provided with offsets to extend through the openings when the member is brought into engagement with the plate for forcing portions of the lacing through the openings.

3. A loose leaf book including cover pages having a lacing for removably securing leaves between said cover pages and one end of the lacing being secured to one of the cover pages,

a base plate carried by one of the cover pages having spaced openings with the lacing overlying said openings, and a movable member hinged to said plate and provided with offsets to extend through the openings when the member is brought into engagement with the plate for forcing portions. of the lacing through the openings, said offsets frictionally bindingthe lacing against the walls of the openings to retain the lacing against slippage and to hold said member in contact with the plate.

4. A loose leaf book provided with cover pages for receiving therebetween a series of loose leaves, and onevof said cover pages having a cutaway portion, a lacing for retaining the leaves between the cover pages, a locking mechanism for'receiving and clamping one end of the lacing mounted in said cutaway portion, said locking mechanism including interfitting sections, each section having a plurality of openings, and means formed on each section for fitting in the openings of the adjacent section for causing the locking of the lacing.

5. A loose leaf book provided with cover pages for receiving therebetween a series of loose leaves, a lacing for retaining the leaves between said cover pages and locking means for the lacing, said locking means comprising a fixed section and a movable section, each provided with a. series of spaced openings and projections, the projections of one section fitting in the openings of the adjacent section for locking the lacing therebetween.

In testimony whereof I affix my signature.

ALBERT R. DANIELS.
